Create a custom Object in Javascript. Create an Object instance. Add attributes and methods.

As follows:
Copy codeThe Code is as follows:
Var person = new Object ();
Person. name = "Nicolas ";
Person. age = "29"
Person. job = "Software Engineer ";

Person. sayName = function (){
Alert (this. name );
};

Person. sayName (); in the preceding example, an object named person is created, and three attributes (name, age, and job) and a method (sayName () are added to the object ()). The sayName () method is used to display the value of this. name. Early JavaScript developers often use this mode to create new objects. However, this method has an obvious disadvantage: using the same interface to create many objects will produce a lot of repeated code. To solve this problem, people began to use a variant of the factory model.
